Provided are an electric handle, an electric toothbrush and an electric cleaning brush. The electric handle comprises a housing, a rear cover, a swing motor and a main control structure. By installing a vibration control mass with limited mass, the rotational inertia of the stator of the swing motor is increased, so that the vibration amplitude of the shell of the swing motor is reduced. It also reduces the vibration amplitude transmitted to the control circuit board, battery and electric handle, decreases the vibration feeling in user's hand, and makes the output shaft of the swing motor transmit effective swing output as much as possible. Then the swing output is transmitted to the toothbrush head or cleaning brush head installed on the output shaft. In this way, the cleaning effect and vibration reduction effect are better, the hand feeling is more comfortable, and the production cost is also reduced.
